This is a 128 swatch color palette I made by sampling several pictures of old copper coins and copper pipes to capture the range of orange and browns of the copper and the diversity of blues and greens that occur from oxidizing.

Use as you would any other color palettes, great for painting aged metal in general, and copper in specific. I painted an old penny as an example of the color set in use. I hope you find use for this palette!
